the same, and has for its object the con-- struction of a tire that willistand the hard-- est usage and retain its resiliency,`while, at

the same time, being practically impervous to punctures suificiently deep to destroy the resiliency of the tire, thus greatly prolonging the life of the cushion tire.

Another object of the invention is to-provide a tire kept resilient by air but ina construction that will prevent the escape of,

the air after the tire construction is finished.v

Another object of the invention is to provide a resilient rubber cushion tire having an air tube encased therein without any ex posedvalves to get'out of order.

With these and other objects in view,

which will be apparent to those skilledl in the tire art. as the description proceds, I will describe the same in connection with the appended drawings in which:

Figure 1 is a sectional view of the tire on the line. 1-1 of Fig. 4; w Fg. 2 is 'a sectional view of a modification at right'angles to the view shown in Fig. 1;v

Fig. 3 is a sectional view of another modiffication similar to the view 'of Fig. 2, and,

Fig. 4 is a. sectional 'view of a tire shown in Fig. 1, the section being at right angles.

.to the sectional view of Fig. 1.

1 represents the tire tread and 2 a 'tube preferably made of rubber, the ends of the tube brought in proximity to'each .other 'at 3, where I may employ a valve construction comprising a short rubber tube 6 small enoughto fit into the meeting ends of the tube 2 and vulcanized therein and having therein a conventional valve a (not shown) fo'w the attachment of a pump to inflatethe tu I i After thetube is inflated and the valveis automatically closed in the usual way by the valve; I t en placethe tube in a moldv and support the same in any 'convenient way and mold the solid rubber tread 1 and pressure of theair thereon and I desire portions 4 around "the tube and casing' 6' so as to form a solid. rubber tire'completely' encasing the smaller tube 6, casing 6' and rubber tube 2, the rubber beingvmolded in a solid airtight mass around the inflated tube is then suitably vulcanized on the tread I and other .portions as desiredand the-tube may be vulcanized to the'surrouiiding casing. 'This construction will prevent 'any possible escape of the air inothe enclosed rubber tube even though the air for any reason leaks through the tube. The rubber also as shown in F 1 encases the valve 3 so that if-the valve should, for any, reason, begin to leak, the air escaping through the same could not escape through the surrounding incasing rubber.

In Fig. 2 I have shown a modification in which I may insert several tubes 2 and mold the rubber around them in the man- 4 ner described relative' to Figs. 1 and 4.

In Fig. 3, I have shown three tubesv encasedin an airtight solid rubber 4casing and a noi-skid device lembedded in the rubbei' trea j. w

My tube 2' may be made of rubber. or I ,may have an inner'rubber tube oovered with a rubberized fabric tube. If I use va rubber tube I may first inflate the tube as full of air as will. conveniently hold and then partially mold a rubber casin around 'it or enclose it with rubberized abric to make it sufliciently strongto hold av greater pres- ,sure of air. Having surrounded the 'rubber tube with this partially completed 'outer casin I then inflate the rubber tube sufficient y full of air to getany pressure de-' sired, I may thenv withdraw the pump con-l nection used in inflating the inner tube and mold around the valve the lcasing 6' completel covering the. valveA inlet' or outlet,

and t 'en complete the rmoldingof the tread 1 and the portions` 4 and vulcanize the completed tube as desired. Of course the amount of pressure of the airin the inner 'tube canv be regulated to adapt the com-- leted tire for different pressures dependmg pon the weight of the vehicle on which the tire is. to be used.

claim is.: w

1. A rubber havin a valve therein, the entire'tube and valve ein encased in rubber, saidrubber being soli at its tread portion-,fand sufli- Havin'g -described my 'invention what I tire bomprising a rubber tube, united atitsend by a smaller tube ciently thick of tself to form a resilient tread, a portion of the surrounding' rubber being also shaped to be clamped by the ordinary tre rim. V

2. The process of making a rubber tire, which consists in inflating a tube through an opening therein, and molding airtight around t a thick tread portion and a. portion adapted to be clamped by ai rm all in one solid piece entirely surrounding the inner tubev and said opening.
